AUDISON The Prima APBX10A2 active subwoofer, with 10 - inch driver, features a dedicated high performance amplification module which enhances all the passive box technologies, such as the 2 Sides / 2 Sounds design, the Plug & Play terminal block and ultra - compact size. The amplification module, with power outputs of 400W RMS is developed with he-li technology (high efficiency / low impedance), which thanks to the absence of the DC - DC voltage booster reaches the impressive 90% efficiency level, very close to the theoretical limit of the D - Class. New input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the he-li (High Efficiency Low Impedance) amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes.

Features

• D - Class amplifier featuring he - li technology (high efficiency / low impedance) without switching power supply, for a performance next to ideal.
• Input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the he - li amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes.
• Defeatable filter to use the sub dedicated output of a bit or AP bit processor.
• High level audio input on multi - pin connector for maximum OEM integration and low level on RCA for aftermarket sources.
• ART turn on function (Automatic Remote Turn - On).
